[Foundation and Higher] Interpret simple expressions as functions with inputs and outputs where appropriate.

[Foundation and Higher] Interpret simple expressions as functions with inputs and outputs where appropriate.. Within Notation, vocabulary and manipulation, this learning objective sits inside Functions for AQA Mathematics 8300. Focus on using ideas such as function, input, output accurately in your explanation. A strong response should define the core idea, describe the relevant calculation, reasoning, representation, and interpretation, and connect it back to the question wording instead of giving a vague definition. When revising, students should aim to explain the subject clearly, include precise precise mathematical notation and terminology, and show how the idea links to the wider topic rather than listing isolated facts.
